So, if you are an absolute beginner in electronics , I suppose there are to many things that I “should “ talk about first, but then again, there are a few notions of elementary physics that we’re not going to cover in any posts on this blog, assuming that whoever is reading this already has them all covered, and by elementary notions I mean common sense electricity and optical physics.
To keep things as simple as we can, so that anyone can fully understand the concept, “electronics” basically means that you have a power supply of some sort, connected to a main board with circuits and other parts that allow electricity to flow trough them thus the machine, the motor , the computer, phone etc, can perform certain operations and functions. Think about the primitive TV for example. No electronic board could and won’t function without diodes, transistors and capacitors for example.
Keeping it simpler than that, do you know who and when he invented the first battery? Well, it was a count! Yes, it was Count Alessandro Volta, and he invented it in 1700’s!
Going back to basic electronics , to understand a board you need its schematic or diagram. The circuits can be organized in series or parallel. Bulbs in parallel get the full voltage of a battery for example.
Another important part of the electronic board is the resistor. These “guys” limit the flow of electricity trough a part of the circuit so that they are useful to timers, to dividing voltages or limiting the voltage of machines that are sensible to high values, more information on www.electroschematics.com/basic-electronics/
Also we talked about transistors. These are by far in my opinion the most important part of modern electronics! They literally revolutionized it! Most of them are used for amplifying a sinusoidal signal. There are polar and bipolar transistors. They also act like stabilizers for high voltage power switches!
